My suggestion is that if u have wood, concrete, or tile floors, don't use a metal stand. This amplifies footsteps through metal. If u have carpet with heavy padding it's fine. But I had to put fiberglass pannels under my cage. This helped tremendously. Wood on wood might also have the same effect. I don't have exoterra to know if they have padded/rubber feet. I assume they don't. But fir WC or skittish frogs, footsteps are freikey!! For that matter so is the vaccume cleaner!!
